Original application filed August 26, 1897, Serial No. 649,632. Dividedand this application filed December 6, 1898. Serial No. 698,4 l7. (Nomodel.)

.To 60% whom it may concern: I

Be it known that I, JAMES STEWART, J r., a citizen of the United States,residing at Peekskill, in the county of Westchester, State of New York,have invented an Improved Sewing-Seam, of which the following is aspecification.

This application is a division of my appli-' cation, Serial No. 649,632,filed August 26, 1897.

The invention relates to an improvement in that style of scam producedby the sewinggoods of double threads and lateral oblique stitches alsoof double threads, said stitches on the under side of the goods beingcoincident with the stitches on the upper side of the goods. In theproduction of the seam the thread is first passed through the goods inthe form of a loop. The goods may then be fed forward the requisitedistance to form a stitch, or the needle may be advanced and the threadagain passed through the goods in the form of a loop, which loop passesthrough the loop of the first stage of the stitch. The thread is thenpassed through the goods in the form of a loop in an oblique lateraldirection to the first two stages of the stitch. The loop of this thirdstage or portion of the stitch passes through the loop of the secondstage of the stitch. The thread is then passed through the goods at thepoint where the second loop is formed in making the first stage of thesecond stitch, and the loop of this stitch passes through the loop ofthe third stage of the first stitch. Thus the loops of the three stagesin the formation of The needle first punctures the goods, as at S, andthe loop S is formed. When the needle leaves the goods after formingthis first stage of the stitch, the feeding forward of the goods mayoccur. The needle then punctures the goods, as at S to produce the loopS on the under side, said loop in its formation being passed through theloop S. The needle punctures the goods, as at S to one side of the othertwo punctures, and the loop S is formed and passes through the loop SThe needle punctures the goods at S again and another loop S is formed,which loop passes through the loop S of the oblique lateral part of thestitch. This second looping S constitutes the first stageor part of thesecond stitch, and the operations as just described are repeated. Itwill be observed from Fig. 2 that there is a peculiar triangular lockingof the three loops of the various stages of each completedstitch, whichaffords great security to the seam and also provides for the flexibilityof the seam before referred to, as said interlocked looped parts of thestitches will be more or less tightly drawn into the goods according tothe quality of the goods being acted upon.

In Fig. 3, A is the hat B, the reed; O, the sweat, and X the line ofstitching. The same parts are similarly marked in Fig. 4.

Of course it should be understood that the sweat may be sewed directlyto the hat without the intervention of a reed and also that the improvedseam is not in any sense'limited to the art of manufacturing hats.

I claim as my invention- 1. The herein-described seam for a sewedarticle, the same comprising a fabric having a straight line of sewingcomposed of a single thread on the upper surface of the fabric, and adouble thread on the lower surface with lateral parts extending from thestraight line of sewing each composed of double threads on both surfacesof the fabric, the double threads of the lateral parts on the uppersurface being directly above the double threads of such lateral parts onthe under surface of the fabric.

2. The herein-described seam for a sewed article, the same comprising afabric having a straight line of sewing and lateral extensions from oneside thereof, each alternate loop of the straight line of sewingembracing a loop of one of the lateral parts of the stitches, the loopsof said lateral parts of the stitches embracing the other loops of thestraight line, which latter loops of the straight line of sewing embracethe first-mentioned alternate loops of the straight line of sewing.

In testimony whereof I have hereunto subscribed my name.
